Mouse Tumor-Associated Endothelial Cells (Mouse Colon Cancer Origin, CT26, MTCLECM) from Creative Bioarray were isolated from pathogen-free laboratory nude mice. MTCLECM from Creative Bioarray were isolated from human xenograft of pathogen-free laboratory nude mice. Mouse Colon adenocarcinoma epithelial cells (CT26) were subcutaneously injected into the nude mice for 4-6 weeks and the tumor tissues were then harvested for cell culture. MTCLECM were cultured in a T25 tissue culture flask pre-coated with gelatin-based coating solution for 2 min and incubated in Creative Bioarray’ Culture Complete Growth Medium generally for 14-35 days. Cells were detached from flasks and immediately cryo-preserved in vials. Cells will be delivered in a frozen vial and each vial contains 0.5x10^6 cells/ml. The method we use to isolate tumor-associated endothelial cells was developed based on a combination of established and our proprietary methods. These cells are pre-coated with PECAM-1 antibody, following the application of magnetic beads pre-coated with secondary antibody.
MTCLECM are tested for expression of markers using antibody, Ve-Cadherin (CD144, VE-Cadherin Antibody, C-19, sc6458 Santa Cruz); or CD31/PECAM-1 (Purified Rat Anti-Mouse CD31, Catalog No. 553370, BD) by immunofluorescence staining or FACS. MTCLECM are negative for bacteria, yeast, fungi and mycoplasma. Cells can be expanded for 3-6 passages at a split ratio of 1:2 under the cell culture conditions specified by Creative Bioarray. Repeated freezing and thawing of cells is not recommended.
Storage and Shipping
Creative Bioarray ships frozen cells on dry ice. On receipt, immediately transfer frozen cells to liquid nitrogen (-180 °C) until ready for experimental use. Live cell shipment is also available on request.
Never can primary cells be kept at -21 °C.
